Description
Technical field
The utility model relates to the maglev system monitoring technical field; Relate in particular to a kind of on-Line Monitor Device of maglev system, be used for the on-line monitoring levitation train when different speed is moved linear electric motors to the normal force and the tractive force of levitation train.
Background technology
Along with the progress of science and technology, huge change has taken place in the track traffic mode.Worldwide produce at present the mode of transportation of linear electric machine traction, comprised magnetic suspended railway, the traffic of linear electric motors wheel track, magnetic levitation aircraft etc.Above-mentioned transit equipment develops rapidly at present, becomes one of the main mode of transportation in this century in the future.The applied levitation train of this mode of transportation is considered to optimal track vehicle of 21 century.
In the low speed magnetic suspension vehicle be a kind of no wheel, rely on attractive force of electro-magnet to make vehicle suspension, and the track vehicle that directly drives by linear electric motors.Because levitation train when operation and track maintenance certain clearance (being generally 1-10cm); Almost there is not rubbing wear; Therefore security of operation, steady comfortable, noiseless can realize full-automatic operation, and environmentally safe; So this levitation train has good performance driving economy and lower maintenance workload, is suitable as very much the urban transportation system.The floating technology of the normal magnetic conduction of low speed during China's magnetic levitation technology exploitation also mainly concentrates on.
Linear electric motors are meant and utilize electric energy directly to produce straight-line motor, can it be envisioned as traditional rotating motor directly to a lateral incision and exhibition from rotor center, and electric rotating machine then becomes linear electric motors like this.Think that perhaps linear electric motors are the infinitely-great electric rotating machines of radius, at this moment the rotating magnetic field in the stator will become the straight line shifting magnetic field, and vehicle will travel forward along with moving of linear electric motors magnetic field.
At present; The general suspension frame mode that adopts 5 essentially identical suspension magnet modules assemblings of structures of middle low speed magnetic suspension vehicle; 5 suspension magnet module assemblings connect through the slide unit of both sides successively; 10 linear electric motors of each car configuration, the traction of vehicle and electric braking are realized through linear electric motors.Therefore, linear electric motors are power sources of middle low speed magnetic suspension vehicle, are one of middle low speed magnetic suspension vehicle critical components.
The suspension frame is the skeleton of structure out of shape, is bearing whole load of vehicle.Its loading transfer is passed on the suspension frame by the suspending power that suspension magnet produces, and the tractive force of linear electric motors acts directly on the suspension frame.
Linear electric motors are when work; Because the angle that electromagnetic force and horizontal direction exist is dynamic change when vehicle operating; Angle is not necessarily 0 °, thereby, not only produce the traction and the electric braking force of vehicle direct of travel; Also produce normal force simultaneously, and can increase along with car speed increases normal force perpendicular to direction of motion.Because normal force and the needed suspending power of vehicle that linear electric motors produce are in the opposite direction, this normal force will the interfere with vehicles suspending power, and needing increases suspension power, influence the stability that vehicle suspension is controlled, and possibly of vehicle can't suspend even.Therefore, linear electric motors are imperative to the dynamic monitoring of the normal force of levitation train and tractive force.
Because linear electric motors are different from electric rotating machine, its real motion state is difficult to simulation.At present, (speed is 0km/h) required tractive force and normal force in the time of only simulating launch train under this state carried out in existing linear electric motors normal force and tractive force research under the ground simulation state.Thereby the normal force that is detected or tractive force compared than big difference with the vehicle actual motion, also can't simulate dynamic air gap of linear electric motors and vehicle dynamic levitation gap, and testing result is very limited with the effect of vehicle suspension controlling Design guidance to the linear electric motors design.
